Description

These QA1 GM Pro Coil Systems are available for 1963-1982 Corvettes and for 1958-1970 Full Size Chevrolet vehicles, including Impalas, Bel Airs and Caprices. They are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling.

Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications.

Available in MOD Series, independent compression and rebound double adjustable, simultaneous compression and rebound adjustable, or drag "R" Series adjustable
